Solve Rate Problems
HSN.Q.1 Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.
HSA.CED.1HSA.CED.1 Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.
This Algebra 1 lesson teaches students how to solve rate problems. The lesson includes research-based strategies and strategic questions that prepare students for assessments. Students will identify whether the problem is a distance addition or equal distance model. Then, they will organize the information using a distance, rate, and timetable, representing unknown values algebraically. Finally, they will set up an equation using distances, solve for the unknown rate or time, find remaining unknown values, and interpret the solution in a complete sentence. In addition to the lesson, there are two pages of Independent Practice and six pages of periodic review.
